To all whom t may concern.' t

VBe* it knownA that LJAMEs M. SEYMOUR, J r., a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements inv Self- Oiling Bearings; and I do hereby declarey the following to be fa full, clear, Aand exact description of the invention, such as lwill enable others skilled in the art to which it the shaft, without the dangervof the lubrin cant or oilrunning down the shaftor leaking out of the oil-receptacle.

The present inventionlhas for its further object to provide vin connection with a shaft, A

a self-oiling bearing .in which'y the stuiing box, the pacln'nggand the' oil-cup all revolve with the shaft, and inrconse'luencey of which, when the stuing box is once made tight, vit remains tight, and any damage by dripping oil is entirely obviated.L

While it may be' rue, that vertical shaftbearings have been made with the shaft e, Y I

' to indicate corresponding parts.

running in and through :a stuffing box attached yto a hanger, and that fork ashort time such ybearings will remain tight, it is a fact that the inevitable wear on the packing caused by theshaft revolving inthe stuffing box, makestheir life short, and` oilleakage soon takes place, it beingquite 'im-t' possibleto keep a stuiiing Vbox tight withl a shaft revolving in it, unless constantly followed up. f

The inventlon has for 'its v*further purpose toprovide an oil-cup rorncontainer of the general cup-shape or 'configuration represented in the accompanying drawingar which precludes thethrowing out .of the oil due to centrifugal force, and the greater the speed of vthe shaft, the more the oil tends to lay in the form of an annular ring at the farthest point inthe oil cup from the center of rotation. v 'w Other objects of the presentk invention not Sp eciication of Letters'atent.

at this time more particularly enumerated will be clearly understood lfrom the following detailed description of the present invention.

With the variousv objects of the present invention in view, the invention consists, primarily, n thev novel self-oiling bearing hereinafter set forth; and, the invention consists, furthermore, in the novel arrangements and combinationsof the several deyvices and parts, all,y of which will be more fully described in the vfollowing specification, and then finally yembodied Vin the clauses lof the claim which are appended to and which form an essential part of the said specification.

The invention is clearly illustrated in the n accompanying drawings, in which Figure .1 is a side elevation of a fragmentary portion of a vertical shaft, a fixed bracket or hanger, Vand a self-oiling bearing employed with the said shaft and theV said bracket or hanger, illustrating one embodiment ofthe principles of the present invention; Fig. 2 is an yenlarged .vertical sec-v tional representation of a portion of the said bracket or hanger, and the self-oiling bearing, withthe shaft represented in elevation; and Fig'. -is a top view of a portion of the bracket or hanger, the self-oiling bearing, and the vertical shaft, said view being made on the same scale as the parts representedin said Fig. 1. n

Similar characters of reference are employed in the said above described views,

Referring now to they said drawings, the

` companying drawings, comprises a suitablyr shaped and laterally extending support or arm, as 2, provided upon its` one end withV `a ring-shaped element or eye 3 adapted to be fitted upon the ysaid fixture or rod 1, and suitably secured thereon in its supporting relation by means of a set-screw 4. Upon its other end-portion the said support or armQ is made with a downwardly extending arc-shaped member 5, formed at its lower portion vwith a ring-shaped' supporting member, as 6.V

rlhis member 6, as will be seen from an inspection of Fig. 2 of the drawings, is made with an inwardly projecting annular seat, as 7 surrounding an opening 8. Mountedjv upon this seat is a ball or roller-bearing 9 of any suitable construction, comprising the members 10 and 10', the ring-shaped member 10 of the said bearing being suitably aflixed upon the vertical shaft 11 so as to revolve with the latter, as will be clearly evident. Mounted upon the said shaft 11, with its lower end resting` upon the upper surface of said ring-shaped member 10, is a suitable sleeve, as 12, and also mounted upon said shaft 11, directly above the upper end-portion of said sleeve 12 is a supporting ring or collar 13, which is securely aflixed to the said shaft by means of a set-screw la. In this manner, as will be clearly evident, the shaft 11 and the ball or roller-bearingv are operatively mounted with relation to the supporting element of the bracket or hanger, and any displacement of the shaft in a downward direction is clearly obviated.

Suitably mounted upon the shaft 11, at a desirable point below the member 6 and the ball or roller-bearing 9, is the neck or sleevelike portion 16 of a suitably-shaped oil or lubricant container, as 15. The said neck or sleeve-like portion 16 is internally screwthreaded, as at 17, its upper chambered part 1S being closed by a wall-portion 19 in which there is an opening 20 into and through which the shaft 11 extends, as shown. Screwed into the lower screwthreaded portion of the saidvneck 1G is a gland, as 2l, and in the said chambered part 18, between the wall-portion 19 and the end of the gland v21, and surrounding the shaft 11 is a packing 22, the whole forminga suitable stuffing box, rotating with the shaft, and thus remaining tight upon the shaft, so that all dripping of thc lubricant from the stuffing box, or the oil running down the shaft is entirely obviated, after the stuffing box has once been made tight, as will be clearly evident from an inspection of Fig. 2 of the drawings.

The upper part of the said neck or sleevelike portion 16 is made with an enlarged hollow ball or cup-shaped element, as 23, the upper portion of which extends annularly and inwardly, as at 24, and has an opening, as 25, into and down which the arc-shaped member 5 of the bracket or hanger projects and extends into the interior or chamber 26 of the said ball or cupshaped element 23, the previously-mentioned seat 7 of the ring-shaped member 6 connected with said member 5, and the ball or roller-bearing being also disposed within the interior or chamber 2G of the said ball or cup-shaped element 23, as illustrated in said Fig. 3.

lf desired, there` may be suitably sccured to the non-rotating arc-shaped member 5, by means of screws 27, or in any other suitable manner, a suitably-shaped scoop or deflector, as 28, which, during the rotations of the shaft 11 and of the said ball or cupshaped element 28, scoops up the oil or lubricant and deflects and conducts the same Vtoward the center of the bearing where it floods the bearing and then runs through the bearing back into the rotating cup, to be again scooped up and deflected and deposited upon the central journal or briaring,y as will be fully understood,

lVhen at rest, the cup is .filled with the lubricant or oil to a `level slightly above the ball or roller-bearing, the annular and inwardly projecting portion Qlof the ball or cup-shaped element clearly preventing any spilling or flying of the oil or lubricant out of the opening 25.

Any further description of the operation of the self-lubricating bearing is deemed unnecessary, the same being fully understood from an inspection of said Fig, 3 of the drawings.

l am aware that some changes may be made in the general arrangements and coinbinations of the various devices andparts, without departing from the scope of the present invention as set forth in the foregoing specilication and as defined in the clauses of the claim which are appended to the said specification. Hence, l do not limit my present invention to the exact arrangements and combinations of the various devices and parts as described in the said specification, nor do l confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawings.
